Merge tag 'nand/for-6.17' into mtd/next
* Raw NAND changes: Various controller drivers received minor fixes like DMA mapping checks, better timing derivations or bitflip statistics. It has also been discovered that some Hynix NAND flashes were not supporting read-retries, which is not properly supported. * SPI NAND changes: In order to support high-speed modes, certain chips need extra configuration like adding more dummy cycles. This is now possible, especially on Winbond chips. Aside from that, Gigadevice gets support for a new chip (GD5F1GM9). Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
